Be it known that I, JACOB P. WRIGHT, a citizen of the United States, and a resident of Barberton, in the county of Summit and State of 0h10, have invented certain new and useful ImprovementsinGlnesApplyin Mechanism, of winch the following is a speci cation.

The present a plioation is a division of en application for letters Patent filed by me June 20, 1900, for an improvement in boxmachines, Serial No. 20,97).

The. subject of the present ap iication relates primarily to mechanism dr appl ipg glue, includinv any liquid cer'nentin rnevum to a strip or b ank of paper or the li e, during the recess of converting the same into bones or s noirs, such mechanism oombini 'eimplieityfof construction with reliability and elicie'ncy-,of operation and being hereinafter particolari set forth and claimed. y

In the diawings, Figure l is a transverse section, partly in elevation, of my improved glne-appiying mechanism. Fi 2 is a vertical section ason the line .2 2 0f ig. 1.

FE is a bracket, com rising a top, bottom, and side, eflixed to tlie frame of the box making machine. On the side of this bracket is s bearin for a horizontal shaft H, which carries a gne-applyin wheel of novel construction, above and adjacent to which wheel extends the strip or blank of paper or the like to which the glue is to be progressively applied. The shaft .H2 is provided with a gearwheel W3, which meshes with and is actuated by the drivinggearin of the box-machine in a manner to revolve t e lne-wheel at a prescribed rate of speed. he iiglne-wheehcom prises an annular portion I2 and several ef uidistant portions K2, having the same ra ius as the portion I2 and extending parallel with the axis of the wheel. The portions Kz constitute the outer or peripheral faces of arms which extend from the wheel-hub in directions that incline from; lines radial to the wheel, the inrlinntion being rearward and outward with reference to the direction 'of rotation of the wheel. 'lho lower portieri of the gluewheel revolves ivithin a gine-pot L, which rests upon a heater M2, secured to the bottoni of the bracket. The bottom of the pot is inclined, so that lle pot is wedgeshaped, and the surface ol' the heater on which such bottom rests is correspondingly Specification of Letters Patent. Serial No. 20,976.

inclined. As a result of the inclination ofthe pot land its su port the pot can Vreadily be slid into or Withdrawn from position beneath the glue-Wheel without the otherwise necessity of removing or shifting adjacent parts notwithstandin the fact that the glue-wheel projects down into the pot. Obviously, if the heater were disposed horizontally the lue-pot could not be removed ress the heater were also ren1oved,which operation would require, as heretofore, a ilexible pipe connection for the heater, together with special' devices for raising and lowering the heater. Just above the glue-pot the gluewheel is engaged by an adjustable scraper N that is designed to remove surplus glue therefrom.

The above-described inclination of the glue-wheel'arms, which carry the glue-applying portions K, prevents such arms lifting glue as they emerge from the pot, for the reason that the angle at which the forward sides of said arms stand on emerging from the pot is such that glue readily passes down oil the same.

Above the glue-wheel is a roller R2, between which and the glue-wheel thepe )er asses, the apex' being guided by a sultahxfsisposed ro ler C', mounted on a shaft i supported by the bracket. To reduce th e paper-engaging surface :of the roller R, 1t is groovecl circumferentially, a. groove r bein provided opposite the: annular portion Is an other grooves r 'ebd 1| being provided o posite the glue-carryingportions K and so that op osite the latter there is a series of narrow carin -siirfaces Asa result of the provision of the circmferential grooves xn the roller, as described, there is no pressure applied to ala eportion of the surface of the paper opposite the glue, and hence .any such s uee'zln action on ther lue is avoided as wou d resuFt in the exudatlon of the glue nt each side of the roller and the formation -thereat on the paperlof raised lines or ridges of lne.

fThe roller Re is journaled in hearings ai* foi-ded by two arms S and S, that are secured upon the to of the bracket F2, preferably by means which permit the ready lifting of the roller ,for the convenient insertion of paper between it and the glue-wheel when such insertion is necessary, As shown, each therefrom nn.
